• Subject: Save/restore Compression algorithms....

Greetings,

We're working on doing some system saves under program/CL control.  One of
the interesting things we found was that a save *nonsys under CL control
specifying DTACPR(*YES) took more time and more tape vs the straight GO
SAVE/21.

Is there a difference in the algorithm being used by software vs hardware?

I can see a definate time/performance difference between the 2, and I'm
curious as to if the newer hardware compression (for a 6385 tape drive in
this case) is different.

Thanks..

Don in DC
